I understand the problem perfectly. The reason for this may be in that an error is occurring. If this is the case then you should inspect the value pointed to by error. Otherwise there may, I suppose, simply be no matching nodes for the path provided.

With this, I could get the title of the articles, but when I try "/rss/channel/item" in order to get other things such as description and things like that, the array keeps empty. This must be a foolish mistake.
